To all whom 'it may concer/n.:

Be it -known that I, FRANCIS C. OsBoRN, a citizen of the United States, residing at Detroit, in the county of W'ayne and State of Michigan, have invented a new and ,useful Improved Paper-Tube Machine, of which the following is a specification.

My invention relates to that type of machines by which continuous strips or bands of paper or other similar material are carried spirally around a mandrel, cemented together, formed into continuous tubes and linally cut off into predetermined lengths.

The objects of my improvements are to provide a machine of this class that can be quickly and easily adjusted for paper of varying widths and for tubes of different diameter; to provide means whereby the tubes are made of two or more layers, the inner surface of the inner layer being evenly coated with paraffin and the inner surfacefof` the outer layer being coated with glue or other cement; to provide means whereby the paraffin and glue will be evenly spread on the strips of material; to provide guides for the paper that are easily adjustable; to provide means to accurately and cleanly cut the tube into lengths and to provide means to quickly dry the cement between the layers of the material. I attain these objects by the construction illustrated .in the accompanying drawings, in which- Figure l isa eneral plan view of the machine. Fig. 2 1s a plan and Fi s. 3 to 7v and 17 to 20 inclusive are detailso the saw driving and guiding means on a somewhat larger scale. Figs. 8, 9, and 16 are details of the driving pulleys of the tube forming belts. Figs. 10, 11, and 12-are details of the paper guides. Figs. 13, 14 and 22 are details of the means for coating the material with cement or paraffin. F ig.' 15 is a bottom view of the tube forming mandrel lshowing the auxiliary paper guide. Fig. 2l is a etail of an auxiliary paper guide.

Similar reference characters refer to like parts throughout the several viewsv of the drawings.

The base or bed A of the machine is similar to a lathe bed and is supported by legs as shown in Fig. 1. On this bed are pivoted the swinging bed ieoes B, and `the arm B. The pivots of the ed pieces B and arm B are in line with each other. To one end of each of the flat bed'pieces B is secureda slidable support F for the pulley P', the disupright bearing K of the stud shaft lo of i the pulley P. On the lower end of shaft 7c is the gear L which meshes with the pinion N on .the shaft C. Inside of the bracket J is the bearing O of the shaft R which shaft. extends across and is splined in a sleeve r, carrying a pinion N which meshes with a second gear L on a second shaft 7c which carries the pulley P at its upper end.

At the head end of the base A is a small bracket a to which is pivoted an arm B which is in turn pivoted to the bearing C on the shaft C. This bearing isheld froml longitudinal movement on the shaft by the collars c. A link D is pivoted to all Athe swinging bed pieces by the screws j, and as the distance between the screws y' is the same as between the pins X of the swinging bed pieces, the several bed'pieces will always remain parallel to each other. The angle between the bed pieces and the base is determined by the graduated screw W supported by the bracket E secured to the base, which screw engages in the nut U which is pivoted at one end of the first bed piece B in line with the screws X and j, and equi-distant from X with j. As will be seen in Fig. 1., the screw W is graduated so the angle between the bed pieces B and the'mandrel can be accurately determined.

The machine is driven froml an over-head countershaft of any desired construction on which countershaft is secured a wide driv-l ing pulley which pulley is connected by means o'f a driving belt with the pulley p.

The belts b pass aroundfthe mandrel M as shown in Figs. 1 and 15 and should be about as wide as the material wound. The hollow mandrel is securely fixed in the Ahead H of the machine. For the purpose of heating the mandrel so that the paraiiin will penetrate the material of the strip and flow into the joint between the spirals and also todry the cement, l provide a steam pipe bent upon itself extending the 'length of the mandrel and having ends m projecting from one end of the mandrel, which pipe ends may be con nected to any steam source.

The means for coating the paper strip with paraiin or glue is designated by G, and

consists of the tank 70 supported on suitable legs, and having secured to it the arms 7l, carrying the pin 72 upon which is mounted the roll of paper 7 3. Journaled on the pin 74 is the roller 75 which dips into the liquid paraliin or cement and carries it up against the lower face of the paper strip. This strip is guided between pins in the holes 76 in the arm 77 pivoted to the sides of the arms 71. The guide roll 78 is supported on the. pin 8O secured in the frame 82 at the upper end of the rod 83. On the pin 81 are secured the collars 84 having fingers 85 which press against 'the coated side of the paper strip. Usually the coating material collects on the outer edges of the strip but by means of the lingers 85 it is spread evenly toward the center.

It will be noticed that by reason of the roll 78 the coated strip will pass to the tube making machine with the coated side up, thus not only avoiding any tendency'ot the coating to form drops as it does when the strip is fed to the machine with the coated side down, but also permitting the coating to level itself on the flat surface.,

To the base, are secured the paper guides as shown in Fig. l, each consisting of a base to which is secured the arm 91 carrying the fixed part 92 of the guide and the slidable part 93, secured to the part 92 by bolts.

An auxiliary guide for the paper strips is shown in Fig. 15 and consists of the spirally arranged gulde 95 secured to the mandrel lvl against which the inner strip of paper, 97, will run, and over this guide 95, to position the strip 96, is secured an arm 98 which bears the guide 99 against which the outer strip 96 will run. With certain grades ot paper, the guide shown in Fig. 21is found to be of great value. lnstead of theshort piece 95 as in Fig. 15, the part 100 ispmade to pass around the mandrel. rlhe paper is Wound upon the spiral sheet of brass 101, which extends until just before the place where the first belt Z) embraces the mandrel.

rlhe mandrel M being of less diameter at this point, the tube will slip around it more easily. The arm 98 and guide 99 are used as before. rlhe part 101 serves a' similar purpose to part in that it acts as a shoulder to force the paper along the mandrel and acts on the inner strip after it has lett the part 100 and after the outer strip has been wound upon it.

The operation of this portion of the machine is as ollows;-'l`he paper strip 97 is carried around through its coating apparatus, through its guide 90 and is wound one turn spirally around the mandrel lvl. The second strip 96 is them brought through to the mandrel and wound around the .tirst strip. The short tube thus formed is then twisted around the mandrel by hand until about haiie a dozen turns have been formed. The edge of the strip 97 is guided bythe ceases guide 95 on the mandrel. After sutlicient tubing has been formed in this manner by hand, the first belt b is put onto the pulleys P and P', and the machinery set in motion, which will cause the belt to continue the work begun by hand, that of pulling the tube around the mandrel. As the tube grows, it will reach the second belt b, where the twisting tension will be repeated, preventing any tendency to untwist. rThe steam heated mandrel will dry the glue before the tube passes oli1 the end of the man drel so that there is no danger of the tube opening up.

The mechanism for cutting the tube into lengths and its operation will be explained later on.

Secured to the end oit the base is an arm h which carries the means for' cutting the tube into predetermined lengths. The outer end of arm L is broadened to '.torm a plate S to which is adjustably secured the table T. The table is sildable on the plate and adjusted 4sidewise by the small setscrews t shown in Fig. 2. Attached to the table T are two arms 1, between which is pivoted the frame 2, securedto the shalt 35, which projects toward the rear end of the machine. (Figs. 2 and 18.) This trame is braced by the cross pieces 50 and the vertical piece 51. ln the upper part ot this iframe is journaled the arbor 10 for the saw for cutting ott the tubes. This arbor is slidable longitudinally in its journals and the position of the saw while cutting is controlled by the following means: lllhe tube as it comes from the mandrel abuts against the plate 14 on the end of the slidable rod 13 as shown in the dotted lines in Fig. 2. This rod is supported by and is slidable in the upper end of the arm 105 15 which iscarried by the revoluble rod 35 and by the arm S carried on the saw arbor. Adjustable collars 52 on the rod .13 position the plate 14 with reference to the saw. rlhe saw arbor is driven by a belt from an over- 11o head pulley to the tlanged pulley 12 on the sleeve 53, journaled in the 'bearing 54 ot the frame 2 (Fig. 20). A 'feather 192 in vthe arbor lreyseat .terms the driving connection between the arbor and the pulley.

' vTo the frame 2 are attached two arms l and 5 which engage cams 55 and 56 respectively on the shaft 29 (Fig. Ll) W hen therefore the shaft 20- is revolved the trame with the saw will be swung toward and away from the tube. ln the outer ends ol the arms l is journaled vthe constantly ruiming screw 3 which is intended to return the saw to its initial position, which screw is constantly driven by means of the pinion 36 125 which meshes with the gear 37 (Fig. 3) secured to the pulley 57, loosely mounted on the end of the shaft 20. This pulley is driven by a belt on pulley 59 on the shaft C as shown in Fig. 1. lThe belt is tightened prevent it: from revolvin ceases by the pulley 60, on the arm 61,l loosely mountedon the end of shaft 20. Secured to the shaft 20 is a disk 38 and loose on the outer end of the shaft is a second disk 39 having a pin 40 which passes through a slot near the end of the shaft. A screw 41 in the end of the shaftw 'contacting with this pin regulates the pressure between the disks and the pulley and the 1frictional stress on the shaft. Secured to the shaft 20 are two collars 27 and 27a, each having a pin 62-62a projecting therefrom, the pins being at an angle to each other on'the shaft and so positioned with reference to the cams, that the dogs 23 and 24 will alternately stop the shaft 20 when the frame 2 and with it the saw is inthe withdrawn and in the operative positions respectively.

The arm 8 lis pivoted on the sanT arbor and positioned by two small collars. To with the arbor it slides ona rod 9 secure to the swinging frame 2. 'Io this arm is attached a short bar 29 (Fig. having a finger 28 which when the arbor, and with it the arm 8 has reached its outward position, contacts with the dog 24, moving it away from the pin 62a and releases the shaft 20, which in turning swings the trame and saw back from the tube by the action of the cams. The dogs 23 and 24 return to position under the iniuence of the sprin sa shown in Fig. 3. On the arm 8 is a sliable plate 30 having a tooth 34 that engages the threads of the screw 3. lug 33 and has its end bent to form the hook 31. The plate is held in its upper or lower position by the spring 64 acting on the lug 65. In the end of the arm 8 is .a pin 26 that is spring pressed outward and is intended to engage the dog 23 and trip the same as the Saw begins to move with the tube.

The operation of the' sawing'mechanisin is as follows When the saw is in the position shown in Fig. 1, the arbor is free to slide under the ressure of the tube against the plate 14. Lihe pin 26 in the arm 8 is to the left ot the dog 23 (see Fig. 3) and the tooth 34 is free from the.screw. Upon the tube pressing against the late 14, the rod 13, the saw, the arbor an arm are moved outward, the pin 26 moves dog 23 with it and pin 62 is released, permitting shaft 20 to turn part of a revolution which through the' action of the cams on the arms 4 and 5 swings the frame 2 and with it the arbor and saw, toward the tube suiiiciently far for the saw to cut through the wall of the tube. In so doing the hook 3lis brought in contact with the threads of the screw 3 causing the plate 30 to be pulled out, the spring 64 acting on lug 65 after passing the center to free the hook from the threads. The saw, arbor, arm 8, bar

This plate also has an upturnedl 29 and finger 28 move with the tube cutting Ythrough the wall of the tube as it turns under the pull of the belts b until the finger 28 contacts with dog 24, moving it to the right, (Fig. 3.-)- which releases the pin 62a and permits the shaft 20 to turn the remainder of the revolution or until the other pin 62 engages dog 23. In this part revolution, the cams swing the frame 2 back from the tube, bringing the tooth 34 into engagement with the screw 3, thus causing the arm 8, the arbor and the saw to be carried to the position shown in Fig. 3. When the pin 26 has passed the dog 23, which it can do owing to the beveled end, the pin 32 on the screw shaft will contact with the lug 33 and force the tooth 34 out of engagement with the screw. The saw will then remain in its withdrawn position until sutiicientlength of tube is formed to again push plate 14 and the rod 13 outward.I rIhe amountof travel to the right and left is regulated by the position of fingers A28 on the bar 29.

To prevent the tube being pulled backby the saw when the frame 2 is withdrawn, I secure the arm 16 to the rigid rod 19 carried by the table T. To this arm is secured the bar 17 with iinger 18 which projects against the tube and prevents it moving to the left with, the saw. (Fig. 7.) To stifen the saw arbor, I secure a bar 66 to the arm 8 and provide a bearing 67. This construction is omitted in F ig. 2 :for the sake of clearness.
